FOXBOROUGH, Mass. — Tom Brady is back practicing with the New England Patriots.

The quarterback who was sidelined almost all last season with a knee injury was on the field Tuesday with most of his teammates.

The Patriots are holding four days of organized activities this week. The first three days were held last week for young players and for free agents who signed in the offseason and need more time to adjust to the playbook.

About 50 players, roughly half the team, took part in the voluntary sessions.
